1. Coloration (Calico):
– Calico refers to a multi-colored pattern that typically includes a mix of red, orange, black, white, and sometimes blue patches.

4. **Temperament**:
– Calico Ryukins are generally peaceful and social, making them suitable for community tanks with other fancy goldfish varieties.

– With proper care, Calico Ryukin goldfish can live for 10-15 years or even longer.
7. Breeding:
– Breeding Calico Ryukins requires a separate breeding tank and careful selection of healthy, mature fish.
